IMPROVEMENT IN SUGAR-MIXING APPARATUS.

Specification forming part of Letters Patent No. 210,769, dated Decemberl0, 1878; application filed October 31, 1878.

To all 'wh-om fit may concern:

Be it known that I, DAVE) EDWARDS, oi' the city, county, and State ofNew York, have invented a new and useful Improvement in Mixing SoftSugars, which invention is fully set forth in the followingspecification, reference being had to the accompanying drawings, inwhich- Figure l represents a longitudinal vertical section of a machineused in carrying out my invention. Fig. 2 is a horizontal section of themixing-cylinder. Fig. 3 is a side elevation oi' the stirrer.

Similar letters indicate corresponding parts.

The sugar discharging from a centrifugal machine usually has diii'erentcolors or shades and is somewhat lumpy, and it is customary to mix thesame for the market so that the product has a uniform color and body.

rlhe object oi' my invention is to provide for mixing the sugar withless labor, greater dispatch, and equal or better results than by themeans usually adopted.

My invention consists of pipes emanating from two or more tanks orcentrifugal machines arranged to discharge the sugar upon an endlesstraveling apron, which discharges the sugar at one of its ends into amixing-cylinder, thereby producing an apparatus which will deliver thesugar into the mixing-cylinder without intermediate handling; further,in the combination, with a mixing-cylinder having a foraminousbotten1,of a stirrer or agitator consisting of a toothed blade or rakefor keeping the mass of sugar contained in the cylinder in a loosecondition, an oblique blade adapted to force the sugar against andthrough the bottom of the cylinder, and one or more propelling-bladesfor keeping the mass in motion, the several blades being secured to arevolving spindle.

In the drawings, the letterA designates the mixer oi'v my machine. Brepresents the endless feed-aprons, and O pipes emanating fromsupply-tanks or centrifugal machines. (Not shown.) In the presentexample of my invention two aprons are used, and the mixer A is situatedbetween the adjacent ends thereof. I arrange the aprons B on rollers al), mounted in brackets D, which are fastened to a beam, E, and posts F.The discharge-pipes O ofthe supply-tanks extend through the beam E, andterminate a short distance above the feedaprons.

A revolving motion is imparted to the apronrollers a b by any suitablemechanism, in a suitable direction to cause the aprons B to move towardthe mixer A, as indicated by arrows, and hence ii' any sugar dischargesfrom the pipes O, it is caught on the aprons and thereby deposited inthe mixer.

By this means I save the labor of shoveling the sugar into the mixer,and am enabled to carry on the operation of mixing sugar with greateconomy.

The mixer A consists of a cylinder or tub, G, which is provided with aforaminous bot tom, c, and with a stirrer or agitator, hereinafterdescribed, by which latter the particles of the sugar dropped into thecylinder are rubbed or forced through the holes in the bottom thereof,the effect of which is that Athe mass is intimately mixed up, and anylumps contained therein are broken up. The process of treating sugar inthis manner forms an iinportant feature of my invention.

The bottom c of the mixing-cylinder is preferabl y made of wire-netting, and made detachable, sothat a bottom having coarser or liner meshesor holes can be substituted therefor.

The stirrer or agitator of the mixer consists of a toothed blade orrake, H, an oblique blade, I, two (more or less) propelling-blades, J,and of a spindle, K, carrying the several blades. The spindle K has itsbearings in the beamE and in a bridge, d, extending across the mixing-cylinder.

When a revolving motion is imparted to the spindle K in the direction ofthe arrow indicated in Fig. 2, the sugar contained in the cyl iuder D isstirred up and kept in a loose conA dition by the action of the rake H,while it is forced against and through the bottom c of the cylinder bythe action oi' the oblique blade I, and at the same time is kept inmotion by the propelling-blades J. The propelling-blades J arepreferably curved, as shown, so as to keep the sugar as much as possiblein the center of the mixing-cylinder.

What I cla-iin as new, and desire to secure by Letters Patent, is-

An apparatus for mechanically conveying sugar from een trfugal machinesor tanks to a mixing-cylinder, for disintegrating the same, consistingin the combination, substantially as hereinbefore set forth, of one ormore pipes extending from the centrifugal machine or tank, an endlessimperforate apron immediately beneath the end of the said pipe or pipes,and a cylinder arranged at the end of and beneath the imperforate apron,and provided with a perforated bottom and a rotary agitating device fordisintegrating the sugar delivered into the cylinder by the endlessapron, as and for the purpose described.

In testimony that I claim' the foregoing I hereunto set my hand and sealthis 26th day of October, 1878.

DAVID EDWARDS.
